I have 4 monitors, so I can have the old task bar with the clock showing. However, I have set the task bar to auto hide, so it is easier for me to just do the method I said.
I also have two clocks that I can glance at, or 3 if I have my BlackBerry PlayBook displaying the time.
Maybe you can set your phone to display the time. My HTC Surround has a kickstand that allows me to easily display the time.
